At 10:00 a.m. on the morning of November 4, 1974, a large lightly built aircraft rose silently from the California desert, it was powered entirely by the solar cells in its wings. The new Age of solar powered flight had arrived. Sunrise, the world's first solar powered aircraft was conceived, designed, built and flown by Astro Flight, Inc., pioneers in the field of electric powered aircraft. Sunrise was designed to use solar power to lift itself to a sufficient altitude during daylight hours to enable it to glide all night and still find itself above the clouds at dawn. In this manner, unencumbered by the limitation of fossil fuels, Sunrise has unlimited range and endurance. This paper describes the air vehicle, structure, power plant, and propulsion subsystems, and gives calculated and measured performance.
